Cloth cutting device

Priority taken;
Country. United Kingdom No. 7232/66 of February 18, 1966

This invention relates to a cloth cutting device and, more particularly, it comprises semi-automatic lay-up r and feeding devices for cloth in connection with a cutting press. With the term cloth are not only conventional woven cloths or woolen cloths, but also products made of synthetic fibers, plastic sheets, Leather, hides, paper, and other flexible products or webs are denied. Mainly are the devices for cutting cloths are determined by those wound on rolls

There are already various known laying and feeding devices for cloth with varying degrees of usefulness, one of the objectives of the present Invention is the formation of devices that work very quickly, economically and space-saving.

The subject of the invention is a cutting price in combination with laying and feeding devices on each Side of the press, characterized in that each placing and feeding device * has the following means, a table with an upper and lower support, which is arranged so vertically movable to either the upper or bring the lower support level with the press so that when there is a table with its lower support is on the same level as the press, the other table is with its upper support is on the same level as the press and each upper support is coordinated so that it is placed on top Material carries when it is raised above the mirror of the press and adapted to act as a feed carrier to serve when lowered to the same level as the press' and each lower support is adjusted to in order to serve as a document for the execution of the material placed on it, which. in and through the press from the: upper Is moved to the other table

To ensure that the invention is properly understood, one embodiment will be described with reference to the accompanying drawings. 009852/0086

Figure 1 shows a side section of the cloth cutting devices with semi-automatic lay-up and feed devices on each side of the cutting press are arranged. ,

FIG. 2 is a top plan view of the devices shown in FIG.

As can be seen from the drawings, the devices comprise a cutting press 10, which has laying and feeding devices 11 and 12 on each side. Since the devices 11 and 12 are identical in operation and design with the exception that they are in working opposite directions will only be one of these are described.

The device 11 consists of a stationary main frame 13, above which a frame 14- for receiving is arranged by one or more cloth rolls 15. On this main frame I3 is a drive head 16, which is movable on rollers 17 in any direction along the frame. The drive head 16 is with the help of the endless drive 18, which extends over the length of the frame 13, driven.

A table 20 is attached to the frame I3, the upper one and has lower support surfaces formed by the roller conveyors 21 and 22. In the same plane with the upper conveyor 21 is a further roller conveyor 23 which extends under the frame 14. Of the

Table 20 carries a cutting table or form cutter 24, which is movable along the upper conveyor 21 and the conveyor 23 by the drive head 16. That End of table 20 which is closest to press 10 has a socket 25 for the removable cloth clips 26. The areas of the brackets act as the starting line for the ends of the fabric layers »

The table 20 is on the frame 13 by means of the hydraulic Lifting cylinder 30 attached, which the table between an upper position, as shown on the device 11 and a lower position, as shown on the device 12, in these two positions the lower and upper conveyors 22, 21, respectively, in a plane with the lower surface of the press 10.

A cutting machine 31 is at the front end of the Frame 14 attached directly above the end of the table 20, apart from the press 10 «

The operation of the device is as follows: With the table 20 in its upper position, a cutting table becomes 24 on the upper conveyor 21, as shown, brought. The drive head 16 is turned to the left in accordance with FIG. 1 driven and pulls the table 24 with it until the right end is approximately under the cutting machine. cloth A series of rolls is pulled from the rolls on the frame 14 along the path of the cutting machine ne 31 and is at the right end of the table 24 by means of Brackets 26 attached. By moving the drive back

to the right is the cloth from all rollers 15 at the same time withdrawn and lies flat on the table 24 until the table 24 reaches its extreme right position. The cutting machine is then triggered and cuts off the cloth and this complete operation can continue for as long be repeated until enough layers of cloth are stacked on top of each other;

It should be noted that the table 24 is not all of its possible way. It can be stopped briefly in its broad legal position, all the shorter Cutting lengths of the cloth, which will avoid waste. A suitable guard is below of the rolls of material attached to the ends of the rolls 15 after being cut from falling off and fouling to keep the carriers 21 or 23,

When enough material has been piled up, the clips 26 are removed. The elevator 30 is then energized to lower the table to its lower position while the cutting table 24 is brought into the same plane with the lower surface of the press 10. The drive head 16 is then actuated in order to guide the cutting table 24 in continuous steps through the press 10 for cutting and to the other side. For this part of the operation, the table 20 of the device 12 is arranged in its upper position, so that the lower conveyor 22 on this side is brought into the same plane as the press 10. The right end of the cutting table 24 is through the 009852/0086

Transporter 22 assists as soon as this appears comes and passes under the lower conveyor 21, which carries its own cutting table 24. As soon as the cutting is complete, the drive head 16 is withdrawn and pushes the Table 24 backwards onto the upper conveyor 21 for unloading * Unloading is carried out with the table 20, which is raised again with the lifting device 30, so that a cutting process by the device can be run and its table 24 through the lower Conveyor 22 can be supported on the device 11.

The two drives of the drive heads 16 are coupled together so that when the table 20 is in its upper position is located, the drive head is only capable of working to move away from the press for loading

When the lower position is reached, the drive head only able to work to move towards the press for cutting · When both tables are in the down position, no drive head can be moved.

The devices described above are unusually useful and have the following main advantages and special features:

Quick stacking of multiple layers of cloth from one or more rolls. Economy in
